A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions object, or the dot3StatsCarrierSenseErrors object. The precise meaning of the count represented by an instance of this object is implementation- specific.

REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 16 } dot3StatsEtherChipSet OBJECT-TYPE SYNTAX OBJECT IDENTIFIER ACCESS read-only STATUS mandatory DESCRIPTION "This object contains an OBJECT IDENTIFIER which identifies the chipset used to realize the interface. Ethernet-like interfaces are typically built out of several different chips. The MIB implementor is presented with a decision of which chip to identify via this object. The implementor should identify the chip which is usually called the Medium Access Control chip. If no such chip is easily identifiable, the implementor should identify the chip which actually gathers the transmit and receive statistics and error indications. This would allow a manager station to correlate the statistics and the chip generating them, giving it the ability to take into account any known anomalies in the chip." ::= { dot3StatsEntry 17 } -- the Ethernet-like Collision Statistics group -- Implementation of this group is optional; it is appropriate -- for all systems which have the necessary metering dot3CollTable OBJECT-TYPE SYNTAX SEQUENCE OF Dot3CollEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A collection of collision histograms for a particular set of interfaces." ::= { dot3 5 } dot3CollEntry OBJECT-TYPE SYNTAX Dot3CollEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A cell in the histogram of per-frame collisions for a particular interface.

For example, a frame which is transmitted on interface 77 after experiencing exactly 4 collisions would be indicated by incrementing only dot3CollFrequencies.77.4.
